Phys.org / Oil dispersants reshape Arctic sea-ice microbes but do not markedly accelerate oil breakdown
By making the Arctic less ice-covered, climate warming has increased both shipping traffic and the risk of oil spills in the region. Changing ice conditions may, however, affect the effectiveness of currently available oil ...
Medical Xpress / Social media algorithms expose many adolescents to self-harm content, study finds
Digital technologies have profoundly transformed how adolescents acquire information and interact with each other outside school. Numerous preteens and teenagers worldwide access social media platforms daily to read posts, ...
Medical Xpress / Protective drug dexrazoxane reduces heart damage in pediatric cancer survivors years after treatment ends
A new study reveals that the cardioprotective drug dexrazoxane significantly reduces heart damage caused by chemotherapy in pediatric cancer patients 15 years or more after treatment ends.
Medical Xpress / A new drug that can potentially overcome cancer therapy resistance
Researchers at Baylor College of Medicine have developed a drug called CS18 that disrupts cancer cells' ability to survive therapy. The findings, published in Science Advances, support exploring the possibility of using CS18 ...
Phys.org / Photocatalytic method cleaves strong C–H bonds while preserving weaker C–Si bonds
α-Silyl alcohols are unique organosilicon compounds bearing a silyl group and a hydroxy group on the same carbon atom. Because these compounds serve as precursors to reactive species, such as carbanions and carbon radicals, ...
Tech Xplore / Apple and OpenAI escalate legal battle over devices
A legal battle between Apple and OpenAI over the ChatGPT maker's secretive device project escalated this week when the artificial intelligence (AI) developer called the iPhone maker's allegations "baseless" and asked for ...
Phys.org / Interlocking molecular propellers create stable 'islands' in artificial lipid membranes
Cells are enclosed by a cell membrane, a sophisticated structure mainly made of lipids that is vital for fundamental biological processes. Artificial lipid membranes have many practical applications, such as drug delivery, ...
Phys.org / Sizing errors can hide true nanoparticle behavior
Nanoscience, which studies small objects, has a big problem. According to a team of scientists at the National Institute of Standards and Technology (NIST), the field confronts a pervasive data analysis error that can give ...
Phys.org / Fossils from Wyoming's Smiley Draw deepen understanding of early primate evolution
A new study from the University of Kansas complicates the picture of primates living in North America some 55 million years ago during the Eocene, a warm period that allowed mammals to diversify quickly.
Phys.org / Webb reveals warped structure in nearby TW Hydrae's protoplanetary disk
Using the James Webb Space Telescope (JWST), astronomers obtained high-contrast coronagraphic images of the protoplanetary disk around the young, nearby star TW Hydrae. Results of the observational campaign, published July ...
Phys.org / Long-term study suggests landfill methane emissions are far higher than estimates
Methane is an especially potent greenhouse gas, causing much more warming than carbon dioxide on a unit-for-unit basis—and a new, uniquely long-term study of emissions at a New Jersey landfill suggests that estimates of methane ...
Phys.org / Attosecond X-ray method maps early electron motions that trigger chemical reactions
All chemistry starts with a push from electrons. In the early moments of a chemical reaction, it's the movement of electrons that initiates the breaking of old chemical bonds and forging of new ones, transforming one molecule ...
